[Koha-devel] Confusion over this bit of code in Circ2.pm

[bob]

Hi,

I am looking at committing katipo koha changes back to cvs and i noticed
this bit of code variation

katipo (older) version:

         my ($resfound, $resrec) =
CheckReserves($iteminformation->{'itemnumber'});
         if ($resfound and not $ignoreRs) {
                 $resrec->{'ResFound'} = $resfound;
                 $messages->{'ResFound'} = $resrec;
                 $dotransfer = 0;
         }
         #actually do the transfer....
         if ($dotransfer) {
                 dotransfer($iteminformation->{'itemnumber'}, $fbr, $tbr);
                 $messages->{'WasTransfered'} = 1;
         }

newer version on Savannah cvs:

         my ($resfound, $resrec) =
CheckReserves($iteminformation->{'itemnumber'});
         if ($resfound and not $ignoreRs) {
                 $resrec->{'ResFound'} = $resfound;
                 # $messages->{'ResFound'} = $resrec;
                 $dotransfer = 1;
         }

         if ($dotransfer and not $resfound) {
                 dotransfer($iteminformation->{'itemnumber'}, $fbr, $tbr);
                 $messages->{'WasTransfered'} = 1;
         }

i'm confused as to what the newer version of code is trying to achieve,
the way i read it (and i might be wrong) is that it is saying that if a
reserve is found, and the ignore reserve is false (ie. do not ignore
reserve), allow dotransfer but then the next bit says if dotransfer and
not reserve found then allow transfer which seems to be contrary to the
first bit

any help to understanding the change will be most appreciated
thanks,
